Doctor William Oliver was an eighteenth century physician who was concerned about the indulgent eating habits of some of his wealthy patients. He invented a biscuit made from flour, milk, fresh butter, malt and hops which became known as the Bath Oliver. It was the first digestive biscuit.
By the late nineteenth century Doctor Oliver's famous recipe and process were owned by Huntley & Palmers.

Osborne Biscuits
These were originally produced in 1860 and were one of the first semi-sweet varieties of biscuit to find mass favour. Initially intended to be called after Queen Victoria, Her Majesty declined to be associated with a commercial product but gracefully suggested that they could name the biscuit after her favourite home, Osborne House on the Isle of Wight.

Gems
These were apparently first produced by accident in the 1850s after some experimental biscuits shrank in the oven. Thomas Huntley liked the result and the product became an instant success, icing being added in 1910. These were some of the smallest biscuits that Huntley & Palmers ever produced and were used in many of the novelty tins.

Breakfast Biscuit
The Breakfast Biscuit was invented by Walter Palmer in 1891. Walter was a scientist who perfected this medicated biscuit using yeast in order to help his friend, George Meredith.
In 1892 the Breakfast biscuit was introduced to France. Within two years the demand for this biscuit was so great, both at home and overseas, that a new breakfast biscuit factory had to be built.
